Sway Control - Learn More

Towing a larger trailer, or any trailer for that matter, can put a strain on your vehicle and your ability to control the vehicle. The slightest gust of wind can feel like you are wrestling with a tornado for control of your vehicle. Keep you, your passengers and your fellow drivers safe on the road with a trailer sway control unit from CURT.

Trailer sway, like any problem, can start small, but if it is not quickly managed, it can turn into a disaster. A trailer can begin to sway back and forth for various reasons, typically when it is pushed by the wind. Whatever the case, trailer sway need not be threat to your driving.


A sway control unit is an inexpensive solution to the problem of trailer sway. CURT sway control kits are designed to attach to your vehicle and trailer at the coupling point and counteract any lateral movement in your trailer, keeping your vehicle and trailer straighter on the road and giving you better control.

The sway control uses an abrasive material like that used in brake pads to provide the necessary resistance while still allowing your vehicle to complete proper turns with your trailer attached. The sway control mounts onto the frame of your trailer and connects to the vehicle’s ball mount using a separate trailer ball.

CURT sway controls are adjustable and easy to install. They come with a sway control unit, a trailer-mounted attachment ball, a hitch-mounted attachment ball, a weld-on tab, a mount reinforcement plate and attachment clips.

Although a weight distribution hitch is not designed to control trailer sway on its own, CURT weight distribution hitches are made to be combined with a sway control unit and many are available with a sway control included for a complete kit. CURT also carries ball mounts that are specially designed to work with a sway control kit, having a sway tab welded right onto the ball mount platform.

We recommend using a sway control any time you are towing a heavier load. While one sway control kit can be sufficient to help correct the problem, two units are recommended for maximum control and stability. CURT also carries a number of sway control replacement parts and accessories to make sure your needs are met. It does not take much to start your trailer swaying. Stop sway in its tracks and make your towing ride as smooth as possible with a CURT sway control.
